Advantages of optical rain gauge over tipping bucket rain gauge

    Rainfall information is the main object of measuring atmospheric environment research and precipitation research , Also environmental monitoring 、 Important indicators and parameters of agricultural safety monitoring . Usually we monitor rainfall , Generally, tipping bucket or siphon rain gauge is used , To perceive the rainfall in nature , At the same time, it is converted into the corresponding switch signal output , It can meet the information transmission in most scenarios 、 Handle 、 Need for recording and display .

    however , The function of this method is relatively simple , By using mechanical equipment to measure rainfall , Although rainfall data can be obtained , But it can't reflect the rainfall in real time , Only the rainfall in a certain period of time can be counted . For some industries that need multiple rainfall data , The function is slightly insufficient . But the appearance of optical rain gauge solves this problem .

 

   IFR202 The type a infrared rain sensor is a non-contact sensor for detecting rainfall through the infrared scanning principle , Inside, the principle of optical induction is used to measure rainfall , Built in multiple optical probes , Rainfall detection is reliable . Different from traditional mechanical sensors , Optical rainfall volume is smaller , More sensitive and reliable , More intelligent , Easy maintenance . Suitable for integration ！ Maintenance free design , It should not be covered by fallen leaves , long life ; High precision measurement index , Small volume , Low power design , Energy saving, multiple interface modes ; high reliability , It can work normally under high temperature and humidity . It can be widely used in rainfall monitoring , Wisdom irrigates 、 The ship sails 、 Mobile weather station 、 Automatic doors and windows 、 Geological disasters and other industries and fields .

 

   
    Tipping bucket rain gauge is also called tipping bucket rain gauge , An instrument for measuring precipitation , The rainfall can be observed in real time . At the same time, the rainfall is converted into digital information output in the form of switching value , To meet the information transmission 、 Handle 、 Recording and display, etc .

   IFR202 Infrared rain sensor is a special instrument for measuring rainfall , Using the principle of optical scanning , Realize real-time scanning of raindrop size and number , Then calculate the rainfall output . Support pulse output and RS232/RS485 Output when using the pulse output function , It can completely replace the tipping bucket rain gauge .
